DESCRIPTION
I needed a simple and fast routine which can detect whether HTTP client is a GUI browser (like Chrome or Firefox), a text browser (like Lynx or Links), or neither (like curl, or L). Hence, this module.
FUNCTIONS
None are exported by default, but they are exportable.
detect_http_ua_simple(@args) -> [status, msg, result, meta]
This function is a simple and fast routine to detect whether HTTP client is a GUI browser (like Chrome or Firefox), a text-based browser (like Lynx or Links), or neither (like curl or LWP). Extra information can be provided in the future.
Currently these heuristic rules are used:
check popular browser markers in User-Agent header (e.g. 'Chrome', 'Opera');
check Accept header for 'image/';
It is several times faster than the other equivalent Perl modules, this is because it does significantly less.
Arguments ('*' denotes required arguments):
env => any
CGI-compatible environment, e.g. \%ENV or PSGI's $env.
Return value:
Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (result) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
